Section 2.2.3 - basis conjugating automorphisms of Fn.

Next Meeting. Wednesday January 25, 2012, 12-2, at Bahen 4010 - Dror will talk about section 2.2.3 (basis conjugating automorphisms of free groups) and then start talking about section 2.3 (finite type invariants).

Announcements. small circle, wide circle, UofT, LDT Blog (also here).

Resources. How to use this site, Dror's notebook.
